Before breakin. Or

If you use a breakin bench of any sort. Break in the engine, then with the pinch bolt loose mock up the fit in your car with the linkage, then tighten up pinch bolts and seal.

You can seal a motor whenever you desire, just make sure you clean the area with motor spray and a rag. I used to seal my motors, but I haven't done it for a while. I used to do it every time I took apart and cleaned my motor. Hope this helps!

Do you seal the carb and pinch bolts while the carb is on?? Or do you take it off apply a think bead at the bottom then push it back into the intake??? same thing with the back plate??? Just apply it around the backplate while it's installed???

Seal while parts are installed. do NOT apply internally

If you take the backplate off and seal the bead, it will work pretty well. You want the sealant to be between the backplate and case. Same thing with the Carb.

no you don't... not with Lucky7 anyway. This is how many ppl suck sealant into their engine. best way to seal a nitro engine with any product you decide to use is a thin bead externally. When sealing use like a coating, not a gasket.

Hmm...I will keep that in mind I guess. I have never had an problems using this technique. If you apply it to the outside, how exactly does it "seal" the engine. If the sealant doesn't get in between the cracks, is the sealant really doing anything? I'm not an expert at sealing motors so any responses will be much appreciated!

That method may work with other sealants that are designed to work like a gasket but as far as my knowledge there is NOT many Nitromethanol safe sealants out there. "Fuel Safe" does not mean NITRO safe so i would test anything you plan to use before you use it. In my time testing and producing engine sealant i have seen WAY to many engines suck many different types of sealant through. some do harm, some don't, but either way this is something to avoid. This is why i decided to make a very thin wicking sealant that would work around easily and fill cracks and crevices. If you notice when using Lucky 7 after it drys it shrinks drastically and may require another coat. This is good! lol

OK. I got my bottle of Lucky7 in hand and have read this thread and a few others. I have yet to find anywhere that says what you use to apply it with. Q tip? paint brush? dump it on and hope it soaks in the right places(LOL)?
